I'm not sure what hobby means but its a fantastic bike. You can ride it on the street some, but try to avoid extended high rpm use as its not really built for that and keep an eye on the oil level. Enjoy one of the best handling and the best suspended off road bike made

I hear you should run a full quart of oil in the tranny side, I guess the manual calls for less. Yanni on this board has numerous dualsport miles on his 450X & would be an exellent source of info for you. His member link is below, just give a PM

I give guided dual-sport tours here in the mountains of WNC/EastTN aboard my '05. 12,000 miles last season...still rollin' hard. Run a full quart in the tranny, swap to SS valves whenever the stock Ti valves zero out, and change your oil when you feel like it. I run regular Castrol 10w-40 on both sides. This bike has been drowned, flipped, and had the wheels ridden off of it. Go to my link in my signature to see all the mods I've done. It's a great bike and will do anything you could ever ask of it.

thank you guys for the info
I changed the oil for the first time after 150 km (100 miles) and I put a little more than in the manual
I will soon put some pictures with the bike
Now it is stock and I run 2-3 miles on road until I reach the trails, so I will not change gearing for the moment.

I will soon try to make it dual sport (blinkers, mirror and a stoplight, a good skid plate) and then I will try to register it.

I am a begineer with this bike (I rode a DR 650 SE and I still have it) and it's powerful and really fun to ride, very light and agile.

Entire quart oil in transmission side only. Also do not overfill engine side as it will push oil into air box. one more thing I do when changing engine side is, after engine stops draining I push kick starter down a couple of times by hand and get quite a bit more oil to drain. I don't use the button for this as I don't want it to start. You have a great bike that requires more maintenance than the old "bulletproof" XR. I broke those too. Remember that the bike carries very little engine side oil so keep the oil changed often and the valves checked.

The CRF 450X is the most popular bike by far where I live, which is 99.9% desert riding. For racing as well as for weekend riding.
I'm one of the weirdos who stays faithful to the 650R, but here are some pics of my buddy's CRF, with the white tank, in full desert trim.

He bought it used after being used as a race bike, it's never given any trouble,

And 3 CRF's at the start of the 5-day UAE desert challenge. I'd say the majority of bikes entered in this race are 450X..
